The Chiefs, who were favored to win, took on the Dolphins at Arrowhead Stadium in Missouri, where Swift was seen sitting next to Donna Kelce, high-fiving fans and dancing to music.

The couple left the stadium just behind Chiefs quarterback Patrick Mahomes and his wife Brittany.

Swift was seen still wearing her custom Chiefs puffer jacket that had Kelce’s number emblazoned across the front, arms and back.

Swift and Kelce, both 34, had arrived at the stadium separately, but the “Cruel Summer” singer later took her spot in Kelce’s suite.

She later rocked side-to-side during the “Swag Surfin’ celebration, based on the hit song by F.L.Y., alongside the suite and Chiefs fans.

The pop star has attended several of the NFL star’s games since September 2023, two months after he first expressed interest in her on his “New Heights” podcast.

In fact, the pair even rang in the new year together by sharing a passionate kiss after she showed up to his earlier matchup against the Cincinnati Bengals.

Though Swift and Kelce have been dating for less than a year, Page Six was recently told they plan to get engaged this summer.

Our insider said the athlete didn’t propose over the winter holidays, which they spent together, because he and the singer “don’t want it to seem like it’s rushed insanity.”

Our source went on to note that Kelce would not be popping the question on Valentine’s Day either for the same reason.

We heard the duo “will get engaged on their one-year anniversary in July.”

The Grammy winner revealed in her Time magazine profile last month that she and the football player “started hanging out right after” he pined for her publicly, which gave them “a significant amount of time” to “get to know each other” before she popped up at his September game against the Chicago Bears.

“I think some people think that they saw our first date at that game,” she explained, adding that they were already a couple by then. “We would never be psychotic enough to hard-launch a first date.”

As Page Six previously reported, Kelce has already asked Swift’s father “for his blessing” to marry her, and the patriarch “has wholeheartedly given it.”
